Strange Sound Comes From The Switch Box

[chandannasta 4]

From Past 2-3 months Zzzzzzz...... sound keeps coming from my switch box. I don know what to do. There are no sparks or anything. the switch box has a surge protector. I will just post the image and let me know what should I do in order to get that noise go away. I have attached all the 3 files

pull the connected Plugs individually, after operating for about 10 minutes, and check if any of the pins is hot.

The first pin from the right hand side is too hot where surge protector is mentioned. If I remove that plug its too hot.

seems to be some loose contact or wiring, check the connections. Else call a qualified electrician.

there are many reasons. loose contact, load on main plug (due to aging), fault in spike guard etc.. you also said that the pin is too hot. so try avoiding that plug and check. otherwise check with other spike guard.

I have heard that Belkins spikeguard is good. Should I purchase that?

don't attach a plug in that particular socket and use for about 10 minutes. If you don't hear the sound, that particular socket is not functioning properly, loose connection/improper contact etc.
